LatestMigratoryInhibitorTechnology-PowerfulCorrosionProtectionofPost-TensionedStructures!MCI®-309 is a powerful Vapor phase Corrosion Inhibitor powder for corrosion protection of ferrousmetalsandaluminuminrecessedareas,interiorcavitiesandvoids.Itprovidesanextremelyefficientdrymethod protectingmetals within an enclosed space. TheMCI® vaporizes and adsorbs on themetalsurfaces, reaching all exposed areas, including recessed sections and interior cavities.

Corrodingrebarindeterioratingconcreteoftencauses costly repairs, financial losses andserious injuries. MCI® technology offers themostcontemporarysolutionsonthemarkettoprevent this from happening. Cortec® MCI®products for concrete maintain structuralintegrity, rehabilitate vulnerable structures,and alleviate environmental concerns. MCI®-309 creates a monomolecular inhibiting layerand enables up to 24 months of continuousprotection.

If the MCI® layer isdisturbed by moisture or by opening the enclosedspace, the layer is replenished by continuous vaporredeposition. MCI®-309 does not contain silicates,phosphates, nitrites, or heavy metals. This easy toapplypowderrequireslittleornosurfacepreparationand prevents further corrosion of pre-coated andpainted surfaces. The layer does not need to beremoved prior to processing or use. The powder canberemovedbyairgunorwater.

Cortec® has had successful applications of MCI®-309Powder for Post Tensioning (PT) Cables. A recentapplication was conducted during rebuilding of theWacoutaBridge inSouthSt.Paul,Minnesota,thewidestbridgeinMinnesotawithregardstothenumberoflanes.
Punalu’u StreamBridge in Hawaii is located stepsawayfromthePacificOceanandtheatmosphereishighly contaminated with chlorides and sulfuricdioxide from the volcano. The acid rain combineswith chlorides to create a very corrosiveenvironment. Injection of MCI®-309 with air wasperformed justafter thepost tensioncableswereplaced. Thepowderdidnotneed tobe removedwhen the post-tension chambers were injectedwithgroutandwerereadilyabsorbedbythegrout.MCI®-309wasusedbecause itenabledprotectionofthesteelsurface,greatlyextendingtheexpectedservice life of the structure.
